Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

Decadal warming rates arising from (i) greenhouse gases and aerosols alone (black); (ii) that obtained including the stratospheric water decline after 2000 (red); and (iii) including both the stratospheric water vapor decline after 2000 and the increase in the 1980s and 1990s (cyan). Stratospheric water vapor and radiative processes.

Study Finds Unexpected Decadal Decline in Global Evapotranspiration, Links It to Moisture Limitation in Southern Hemisphere

Green Car Congress

The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa and South America, have been drying up in the past decade, according to the first major study of evapotranspiration on a global basis. This is the first time we’ve ever been able to compile observations such as this for a global analysis.

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

To analyze this, Wang headed to Switzerland as a member of the CLOUD collaboration to test his experiment at the European Council for Research Nuclear (CERN). All of the scientific uncertainty around climate change relates to clouds in one way or another, said Wang’s advisor and co-author Neil Donahue, professor in chemistry.

A Roomba for Rivers

Cars That Think

Humankind is enamored with water. The machine, which can run autonomously or at the direction of a remote operator, goes around collecting the junk and gunk (like plastic bottles, oil spills, and algae) that float on the water, as well as detritus located up to 10 meters below the surface. Roomba for Rivers.

IEEE Discusses 6 Simple Solutions to Climate Change at COP27

Cars That Think

Simple, effective solutions that can help lessen the impact of climate change already exist. Rahman, a power expert and professor of electrical and computer engineering at Virginia Tech , is the former chair of the IEEE ad hoc committee on climate change. One type is the ultrasupercritical coal-fired steam power plant.
